3D Spectral Nonrigid Registration of Facial Expression Scans

Jean-Philippe Thiran, Hazim Kemal Ekenel, Gabriel Louis Cuendet, Christophe René Joseph Ecabert, Marina Zimmermann

In this paper, we introduce a new template-based spectral nonrigid registration method in which the target is represented using multilevel partition of unity (MPU) implicit surfaces and the template is embedded in a discrete Laplace-Beltrami based spectral ...

Visual Speech Recognition Using PCA Networks and LSTMs in a Tandem GMM-HMM System

Jean-Philippe Thiran, Marina Zimmermann, Mostafa Mehdipour Ghazi

Automatic visual speech recognition is an interesting problem in pattern recognition especially when audio data is noisy or not readily available. It is also a very challenging task mainly because of the lower amount of information in the visual articulati ...
